I may have missed this as I am sitting in Montreal airport after missing my connection with no sleep, a nasty case of jet lag, and an inbox that is sprialing out of control so I may have just overlooked it.

At one point you could change the footprint library file without performing the file write through the fp-lib-table and the next time you accessed the library, it would recognize the file was modified and reload the cache.  Please make sure this behavior is not broken.
